sound loss and mouse goes weird!

don,t really know if this is a hardware or software issue or maybe
both,but something is one card shy of a full deck!
i lose all sound and mouse movement gets erratic after the comp.
has idled for awhile,just goes south! so far i can reboot and viola!
good sound and the mouse behaves! but something is wrong and
i need help figuring out what it is! my system specs follow:
amd 950 t-bird not o/c
ecs k7s5a mobo w/ orig bios
inno geforce 2 ti w/ 23.11 drvs 255/406
maxtor 30gig @ 7200 rpm
phillips accoustic edge sound card w/ xp drvs
logitec 2x optical mouse
winxp home ed
norton internet sec &antivirus 2002
this problem didn't appear until after i installed norton and the accoustic edge sound card. device manger says everything is working ok
my temps are 13c/33c/43c according to mbm5 and sisoft sandra
can any one advise please! thanks da rock

I don't know what is wrong with these ecs motherboards ... do you happen to have also the integrated soundcard?
I also have problems with sound (it doesn't stop but it chrisps) and mouse (the scrolling wheel stops responding)

there have been alot of issues w/this board and amd 1.0-1.4
gig cpus, most common are the cold boot and fsb issues, i haven't
seen to many that involve pci sound , i have onboard sound dis-
abled and use the onboard lan which works great.
i think i remember seeing a post in this forum regarding sb live,
if i understand your specs and you're using sb then you might want to look here for answers to your noise prob.
thanks for your reply!
